` 6 Claims.

" This invention relates `to building construction and, moreparticularly, to improved means for securing metal sheathing `to amasonry or other type of wall structure.

Itis one oi the objects of the invention to provide means for "securingmetal sheathing to a wall structure so that the sheathing will beadequately supported at frequent intervals and also prevented frombuckling as a result of expansion andcontraction due to changes intemperature. e

A further object oi the invention is to provide a methodof securingmetal sheathing to a wall that will be water-tight and relatively simpleand e, inexpensive in its application.

vide an exterior surface that will be novel in 2o appearance and conformto the architectural trend in modern building construction.

Other objects of the invention and the features of novelty will beapparent from the following description, taken in connection with theaccom- 25 panying drawing, of which Figure 1 is a fragmentary sideelevation oi a wallvstructure embodying my invention, a portion of thesheathing being broken away;

Fig. 2 is an enlarged detail section on the line '2 2 of Fig. 1;v

Fig. 3 is a view similar to Fig. 2 but showing the arrangement of thesheathing prior to forming the lock seam in the edges of the panels;

Fig. 4 is an enlarged detail section on the line 4-4 of Fig. 1, and

Fig. 5 is a view similar to Fig. 2 but illustrating the application ofthe invention to a wall made of lumber.

Referring to Figs. 1 to 4 of the drawing, 10 indicates a masonry wallbuilt up of units, such as cement blocks or bricks with the usual mortarjoints. Heretofore much diiiiculty has been eX- perienced in applyingmetal sheathing, such as copper, to a wall of this kind so that it willbe fis g width of the metal panels that are to be used, but

a satisfactory vertical spacing of the strips 11 (Cl. 72-16) i would beapproximately twelve inches. The strips 11, as shown in Figs. 2 and 3,extend into4 the joints a sufficient distance to be rmly anchoredtherein and project from the face of the wall a distance which isvariable, but which I prefer to make approximately one inch and, inorder that the strips ,1l may have ,the requisite stiffness, I prefer touse #l0 gauge steel.

At intervals along the strips 11, I provide ilexible metal tongues 12,preferably of copper and about two inches wide, and these tongues extendinto the joints between the wall units a suliicient distance to befirmly anchored therein and, in order to have a secure anchorage, thetongues may be crimped or corrugated as shown at 13. These 'tonguesalsoare of sumcient length to project beyond the outer edges of thestrips 11 a vsuiiicient distance. to be interlocked in the seam betweenthe panels of the sheathing, which will be later described in detail.

Between the successive strips 11, I place the panels of the sheathingmaterial, such as copper. 'These panels may bejof any desired lengthand, for the sake of economy, it is usually desirable to employ standardcommercial lengths, such as six or eight feet. These panels are.indicated at 14 and have outwardly projecting flanges 15 along theirlongitudinal edges. As will be seen from Fig. 2, the flange on the loweredge of the panel 14 rests upon the strip 11 and the flange on the upperedge of the panel will abut against the underside of the strip 11 whichis immediately above. The strips 11 vthus support the weight of thepanels and there is no tendency for the portion of the panels which isagainst the wall surface to separate therefrom.

As the panels are initially positioned on the strips 11, the anges onthe panels are arranged substantially as shown in Fig. 3, with the edgesof the flanges projecting beyond the edge of the strip 11 a suincientdistance to permit these edges to be folded into the double lock-seamillustrated at 16 in Fig. 2. In forming this double lock-seam, thetongues 12 are folded into the seam and thus the flanges of the panelsare held against outward movement on the strips 11 and away from thewall surface. By forming the double lock-seam as shown in Fig. 2, aweather-proof joint is obtained without the necessity of soldering andthe steel strips 11 will thus be thoroughly protected f and thestructure will last indefinitely.

While I prefer to arrange the double lock-seam 16 along the outer edgeof the strip 11 and substantially in the plane of the strip, this is noty sheet metal work, may be used and the seams may be located whereverdesired on the projecting portion of the strips 11.

In order to permit vertical expansion of the panels 14, withoutbuckling, one or both of the corners 17 between the flanges of the paneland the body thereof may be spaced slightly away from the strip 1l andthe arrangement of the flanges 15 and the tongues 12, which are notdirectly attached to the strip ll, permits the flanges to expand bothlaterally and longitudinally without distorting the body portion of thepanel which is against the wall surface.

In the form of the invention illustrated in Fig. 5, the wall is made ofboards or planks 18 of natural wood or articial lumber and thepanel-supporting strips 19 are bent into the form of an angle sectionwith the vertical leg on the inner side of the boards 18 and securedthereto by nails 20, screws or any other suitable means. The tongues 21,which are for the same purpose as the previously described tongues 12,have their inner ends bent against the inner side of the boards 18 andnailed or otherwise secured thereto as shown at 22. The panels 23 arethen laid and secured in position as previously described.

While I have illustrated and described what I now consider to be thepreferred embodiment of my invention, it will be apparent that variouschanges may be made in the details of construction and arrangementwithout departing from the spirit of the invention which is defined inthe appended claims.

Having thus described my invention, I claim:

1. In building construction, a wall, a plurality of spaced stripssecured to said wall, flexible metal tongues spaced at intervals alongsaid strips and secured to said wall, panels of metal sheathing on saidwall between said strips and provided with flanges on their oppositeedges abutting the strips, and the fianges of said panels on oppositesides of each of said strips being joined together and to said tonguesalong the outer edge of the strip.

2. In building construction, a wall, a plurality of spaced stripssecured to said wall, flexible metal strips, and the iianges of saidpanels on opposite sides of each of said strips being folded intointerlocking arrangement and having said tongues interlocked therewith.

3. In building construction, a wall, a plurality of spaced stripssecured to said wall, flexible metal tongues spaced at intervals alongsaid strips and secured to said wall, panels of metal sheathing on saidwall between said strips and provided with fianges on their oppositeedges abutting the strips, and the flanges of said panels on oppositesides of each of said strips being folded into interlocking arrangementalong the outer edge of the strip and in the plane of the strip andhaving said tongues secured thereto.
